Street Lights Can Cause Long-Term Ecological Changes, Study Says
May 24th, 2012 by 
The presence of artificial street lights can alter the behavior of ground-dwelling invertebrates and insects and ultimately change the structure and function of some ecosystems, according to a new study.
In a series of tests in Cornwall in western England, researchers from the University of Exeter used 28 traps to capture 1,200 animals on the ground beneath street lights and in darker areas between the lights.
According to their findings, published in the journal Biology Letters, invertebrate predators and scavengers were more common underneath the lights, even during the daylight hours.
Thomas Davies, a researcher at the University of Exeter and lead author of the study, said these findings suggest that nocturnal behavior is affecting habitat preference overall, and could have implications for critical ecosystem services, including pollination and the breakdown of organic matter.
“It’s amazing how long we’ve been using street lighting and artificial lighting, and how little research has been done on the impact of those lights on the environment,” he told BBC News.

something tells me that where you have massive use of street lights, you’re not gonna have a “critical ecosystem”.
looks somebody needed to use up their grant money…
